Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal devices, in particular to a palm-type centrifugal device for testing. Background Art

[0002] In the field of biomedical research and clinical diagnosis, laboratory centrifugal equipment plays a vital role. These devices can separate substances of different densities through the centrifugal force generated by high-speed rotation. They are widely used in a variety of experimental operations such as blood component separation, cell culture, DNA extraction, protein purification, etc. Take veterinary testing as an example. In the process of animal disease diagnosis and treatment, blood, urine, tissue samples, etc. are often required to be quickly and accurately tested and analyzed. Especially in animal hospitals or field sites, due to space and equipment limitations, large centrifuges often cannot meet the needs of instant testing; in addition, animal diseases often require rapid diagnosis and treatment, which requires a test device that can respond quickly, is easy to carry and operate, and the palm-type centrifuge device for testing came into being; this device, with its small size, portable characteristics and easy operation, provides great convenience for veterinary testing. It can not only be used in animal hospitals, but also can quickly process and analyze samples in the field, greatly improving the efficiency and flexibility of veterinary work.

[0003] For example, Chinese patent CN219765648U discloses a palm-type centrifuge device for laboratory use, including a centrifuge box, the four corners of the bottom of the centrifuge box are fixedly connected to support legs, the center of the bottom of the centrifuge box is fixedly connected to a first motor, the output end of the first motor passes through the inner cavity of the centrifuge box and is fixedly connected to a test tube placement rack, which can avoid the problem of the palm-type centrifuge device easily tipping over and causing the material to spill. However, the above palm-type centrifuge device has the following shortcomings when used in practice: first, the device lacks a structure for limiting and fixing the test tube during the centrifugation process. During high-speed rotation, the test tube may not be stable enough and is easy to shift or slide out, causing sample damage or spillage, affecting the accuracy and safety of the experiment; in addition, the device lacks a sealing function.

Through the cooperation of the centrifugal bracket 6 and the centrifugal fixing mechanism 7, it not only ensures the stability of the sample test tube in high-speed rotation, but also provides the flexibility to adapt to test tubes of different specifications, significantly improving the efficiency and accuracy of centrifugal testing. Whether in veterinary testing or field environments, on-site sample analysis can be carried out quickly; at the same time, through the ingenious design of the adjustment component 4, the convenient opening and closing of the top of the test box 2 is realized, providing the operator with the possibility of quickly loading and unloading sample test tubes, while ensuring the sealing and safety of the centrifugal process.

[0035] In one embodiment, for the centrifugal support 6 and the centrifugal fixing mechanism 7, a rotating shaft 601 is provided at the bottom end of the centrifugal support 6, and the rotating shaft 601 is connected to the output end of the palm-type centrifugal motor 5, and a plurality of circumferentially arranged fixing holes 602 are provided at the top of the centrifugal support 6 (in addition, in specific applications, the fixing holes 602 are fixedly connected to the outer side of the fixing sleeve 701); the centrifugal fixing mechanism 7 includes a plurality of fixing sleeves 701 arranged at the top of the centrifugal support 6, a mounting groove 702 is provided at the top of the fixing sleeve 701, a clamping assembly 703 is provided in the mounting groove 702, and the clamping assembly 703 includes an elastic ring 7031 arranged in the mounting groove 702 (in addition, in specific applications, the elastic ring 7031 is made of rubber material, which can provide good elasticity and friction), a clamping port 7032 is provided at one end of the elastic ring 7031, and an arc-shaped fixing connected to the fixing sleeve 701 is provided on the outer side of the other end of the elastic ring 7031 The arc-shaped fixing piece 7033 is fixedly connected to the inner side of the fixing sleeve 701 in a specific application, and arc-shaped elastic pieces 7034 matching with the clamping opening 7032 are symmetrically arranged at both ends of the arc-shaped fixing piece 7033 (in addition, in specific applications, the arc-shaped elastic piece 7034 is made of stainless steel metal sheet, which has good elasticity and strength, and can withstand high-frequency deformation without fatigue fracture), a fixing ring 7035 is arranged on the outer side of the arc-shaped elastic piece 7034, a fixing column 7036 is arranged on the inner side of the fixing ring 7035, and an adjusting bolt 7037 is penetrated through the middle part of the fixing column 7036 (in addition, in specific applications, a threaded groove matching with the adjusting bolt 7037 is opened in the middle part of the fixing column 7036), thereby achieving the stability and safety of the test tube during the centrifugation process together with the centrifugal support 6, and providing a flexible clamping system to adapt to test tubes of different specifications and meet the diversified needs of veterinary testing.

[0036] The working principle of the centrifugal bracket 6 and the centrifugal fixing mechanism 7 is as follows: the rotating shaft 601 is arranged at the bottom end of the centrifugal bracket 6, and the rotational power generated by the palm-type centrifugal motor 5 is transmitted to the centrifugal bracket 6, thereby driving the fixed sleeve 701 in the fixing hole 602 to rotate through the centrifugal bracket 6 to achieve high-speed rotation. The fixed sleeve 701 is used to accommodate and support the clamping assembly 703, and is the basic structure for fixing the animal sample test tube. The mounting groove 702 is opened at the top of the fixed sleeve 701, and is used to install the clamping assembly 703, which is convenient for adjusting the clamping assembly 703 to fix the animal sample test tube. The elastic ring 7031 is arranged in the mounting groove 702, which is elastic and convenient for adapting to animal sample test tubes of different diameters. The clamping mouth 7032 is opened at one end of the elastic ring 7031 to provide a larger deformation amount, arc The fixing piece 7033 is connected to the other end of the elastic ring 7031, and is used to support the arc-shaped elastic piece 7034. The arc-shaped elastic piece 7034 is symmetrically arranged at both ends of the arc-shaped fixing piece 7033, and cooperates with the clamping mouth 7032 to provide uniform clamping force through elasticity, thereby ensuring that the animal sample test tube is firmly fixed and providing elastic clamping force. When the adjusting bolt 7037 is rotated, the fixing columns 7036 at both ends are driven to approach each other, thereby driving the arc-shaped elastic piece 7034 to bend through the fixing ring 7035, and the arc-shaped elastic piece 7034 drives the elastic ring 7031 to deform, thereby clamping and fixing the animal specimen test tube placed inside. In this way, by adjusting the clamping force, it can adapt to animal specimen test tubes of different sizes in veterinary testing and ensure the stability of the test tube during centrifugation.

At the same time, the centrifugal effect can be observed through the observation glass 3 on the outside of the test box 2, and the centrifugal condition and stratification effect of the sample in the test tube can be observed in real time.
